Problems solved by technology
However, when the opening is large, the pried opening is easy to slide, resulting in failure to pry the opening
In order to solve the problem of sliding, some retractors make the contact position of the bridge opener and the surgical opening very sharp. However, the retractor is easy to damage the muscle tissue and skin tissue of the surgical opening.
Moreover, the current retractor is manually operated, and the size of the surgical opening is not easy to control

Embodiment Construction
[0036] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0037] Such as figure 1 As shown, a medical robot retractor 100 provided by an embodiment of the present invention includes: a control assembly 110 , a control pull wire 150 and two levers 130 .
[0038] One end of the lever 130 is a pulling head 131 , and the other end is a connecting head 132 . The connecting heads 132 of the two levers 130 are fixedly connected. An attachment control pipe extending along the prying bar 130 is opened inside the prying bar 130 , and one end of the attachment control pipe penetrates the pulling head 131 to form a first attachment control port 1331 on the pulling head 131 . Between the pulling head 131 and the connecting head 132 of the lever 130 is a retracting control section 134 bent outward, and a first retracting control position 135 is provided on the side of the pulling control section 134 away from the other lever 130 .

The present invention discloses that the embodiment of the present invention provides a medical robot retractor, which extends the two retracting heads of two prying rods into the operation opening, and then rotates the retracting control end so that the control pull wire is fixed on the retracting control end. One end of the end is wrapped around the retracting control end, thereby pulling the retracting control segment to change the distance between the two retracting heads of the two levers, thereby retracting the operation opening. The longer the length of the control pull wire wrapped around the retraction control end, the more the two retraction heads are separated, and the greater the opening of the retraction operation opening is, that is, by controlling the length (number of turns) of the control pull wire wound on the retraction control end, To control the strength of pulling the retraction control section, and change the distance between the two retraction heads to realize the control of the size of the retraction operation opening. By setting the first attachment control port on the retraction head, the first attachment control port can absorb the skin or muscle in contact with the retraction head through the first attachment control port by controlling the pressure in the conduit.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a medical robot retractor. Background technique [0002] In the field of medical technology, the retractor is used to pry open the surgical opening of the patient's epidermis, exposing the position under the epidermis that needs to be operated on, so as to facilitate the operation. Now, the retractor is through two prying parts that can be opened and closed, and the size of the operation opening is adjusted by adjusting the distance between the two prying parts. However, when the opening is large, the pried opening is easy to slide, resulting in failure to pry the opening. In order to solve the problem of sliding, some retractors make the position where the bridge opener contacts the surgical opening very sharp. However, the retractor easily destroys the musculature and skin tissue of the surgical opening like this. And the current retractor is manually operated, and the size ...
